Description

A kind of heat engine

Technical field

The utility model relates to a kind of power plant, specifically a kind of heat engine of low-temperature.

Background technique

Thermodynamic theories is thought: " heat can change merit into, and merit also can change heat into, when a certain amount of heat disappears, certainly leads to the merit of respective amount, and when consuming a certain amount of merit, corresponding with it a certain amount of heat must occur "; " the basic condition that heat energy is converted into mechanical energy is that all have the place of temperature difference can both produce power ... heat energy is converted into mechanical energy continuously needs two thermals source that temperature is different at least ".Current various heat engines all are to do low-temperature heat source with air under the normal temperature or water, must have a high temperature heat source that is higher than ambient temperature that heat energy is provided simultaneously, and the part of the heat energy that is provided is transformed into mechanical energy.As, with water is the steamer of medium, must there be the high temperature heat source that is higher than ambient temperature that heat energy is provided during its work, this high temperature heat source provides the temperature of heat energy must be greater than 100 ℃ of the normal points of water, that is to say, its necessary condition is: existingly can make liquid water absorb that heat becomes high-pressure and high-temperature steam and the external high temperature heat source of work done, the low-temperature heat source that becomes liquid water after the steam heat release work done is also arranged.The heat engine of this structure is very high to the requirement of high temperature heat source, and the heat in the high temperature heat source that can't temperature is lower is converted into mechanical energy.

The model utility content

The purpose of this utility model is exactly to provide a kind of at the heat engine low to the temperature requirement of high temperature heat source, the heat energy in the high temperature heat source of lower temperature is converted into mechanical or electrical energy output.

The utility model is achieved in that the upper/lower terminal at back-shaped pipe is equipped with sprocket wheel, is connected with the air bag of splendid attire low-boiling point liquid on the chain that is socketed between two sprocket wheels; Be provided with heating equipment on a standpipe of back-shaped pipe, another standpipe of back-shaped pipe is provided with cooling unit; On upper sprocket wheel or lower sprocket, be connected to pto.

The utility model in use, first carrying liquid in back-shaped pipe, liquid level height is lower than ring top in the back-shaped pipe, under the heating of heating equipment, the fluid temperature in the heating standpipe of back-shaped pipe rises, the temperature of the low-boiling point liquid in the air bag increases.The low-boiling point liquid that temperature raises is partly vaporized, thereby makes air bag begin to expand, and the air bag of expansion upwards floats under the floating function of back-shaped liquid in pipe.The air bag that floats drives upper and lower sprocket wheel by chain to begin to rotate.In the process that air bag rises, the bottom has air bag to forward in the heating standpipe with chain again, and the expanded by heating come-up.The air bag on its top then goes in the cooling standpipe of back-shaped pipe with sprocket wheel.Liquid in the cooling standpipe is owing to be subjected to the effect of cooling unit, temperature is lower, the air bag (low-boiling point liquid) that enters the cooling standpipe carries out heat exchange with the cryogenic liquide that cools off in the standpipe, low-boiling point liquid temperature in the air bag reduces and the beginning condensation, the volume of air bag dwindles gradually with the condensation of liquid, thereby the buoyancy of air bag is reduced, under chain drives, pass the cooling standpipe, progressively to the motion of heating standpipe.Under the alternating action of heating equipment and cooling unit, a plurality of air bags just drive sprocket wheel cycle rotation in back-shaped pipe like this, and the sprocket wheel of rotation is by the pto outputting power.

Heating equipment of the present utility model is the helical heating pipe that is positioned at back-shaped pipe; Cooling unit is the spiral cooling tube that is positioned at back-shaped pipe.Helical heating pipe and spiral cooling tube simple in structure, and can better play the effect of heating and cooling.

The utility model also can be connected to the outer circulating tube that is communicated with this standpipe upper/lower terminal on the sidewall of the heating standpipe of back-shaped pipe, water pump is housed on outer circulating tube.By adding outer circulating tube and water pump, can quicken to heat the heating process of standpipe, improve working efficiency of the present utility model.

The utility model also can be realized like this: sprocket wheel wheel shaft hollow, on upper and lower two sprocket shafts, be provided with the ventilation sprocket wheel that is communicated with wheel shaft, and the ventilation sprocket wheel of bottom is provided with ignition mechanism; On air bag, be provided with suction port, toggle switch is housed on the suction port.After adopting such structure, when air bag passed through the ventilation sprocket wheel of bottom, the gear teeth of sprocket wheel were pushed the switch of air bag suction port aside, imported inflammable gas by wheel shaft, ventilation sprocket wheel in air bag then, utilize the ignition mechanism on the ventilation sprocket wheel that inflammable gas is lighted at last, and off switch.Inflammable gas acutely burns in air bag and produces a large amount of gas and heat, the low-boiling point gas of gas that burning generates and vaporization at high temperature sharply expands air bag, it is floated fast, and then quicken the rotational velocity of air bag, sprocket wheel and generator, add high-power.Air bag rises to ventilation during wheel shaft, on the wheel shaft of ventilating push the switch of air bag suction port aside, make gas in the capsule by ventilation sprocket wheel, sprocket wheel; Wheel shaft is discharged, and quickens the rate of descent of air bag in back-shaped pipe cryogenic riser.

The utility model utilizes the high and low temperature thermal source alternately to regulate the temperature of liquid in the air bag, make alternately vaporization, the condensation of low-boiling point liquid in the air bag, thereby change the volume of air bag, realize that air bag drives sprocket wheel rotated, heat energy was converted into mechanical energy in back-shaped pipe purpose.The utility model can run well under the situation that does not need the big temperature difference, and the high temperature heat source that has solved lower temperature is difficult to be converted into the difficult problem of kinetic energy.The utility model is simple in structure, and cost is lower, suitable utilization and extention.
